I have a relation table named Table_Role_Process (trp) which set Table_Role (tr) and Table_Process (tp) in relationship to each other.

trp has a column trp.Role_ID and a trp.Process_ID (and some more).

I want to display the Table_Role columns in a JSP but some columns should be fedded by Table_Role_Process (and all columns may be editable).

How do I have to code this association in the hbm.xml file?

Where can I find good information about the different association types (

http://www.hibernate.org/hib_docs/v3/reference/en/html_single/ is not a really good one explaining these kinds of associations)?
